He also invites Claire's other patients to the party, telling them to forget their inhibitions and to just have fun.

On one side, he encourages a man to use a ""sure score"" pick-up technique that gets him the woman he wants but leaves him distressed and disgusted with himself for he feels he cannot be with a woman that would fall for such a trick. On the other end of the tunnel, his friend and roommate Champ is starting a new relationship and Trevor can't help but intervene - and in ways that pushes the woman away rather than bring her closer. And somewhere in the middle, Trevor himself is caught up in a strange relationship with Helen Davis, a woman he met at the bar.
